Communication with Andrew was very efficient.

The apartment is as in the pictures: clear, sunny, tastefully furnished. Everything is convenient and there is plenty of small perks available (water, chocolate, guide books).
Location is nice, 3 minutes away from the BTS.
I will certainly be there again if possible

On a total different note and TOTALLY unrelated to the apartment or Andrew, but I feel the need to warn future customers.
The apartment is sharing some facilities with the hotel. The main gate clerk will call a taxi for you from the main road when needed. (someone from the hotel is hailing a taxi on the main road)
When I asked them to hail a taxi for me to the airport, the taxi was there 2-3 minutes later. However the meter was hidden by a piece of rag. I had to ask the hotel to ask the driver to switch on the meter. But the driver just pretended to start it by touching the meter, keeping it hidden by the rag. So I couldn't see anything. I decided to get out of the cab as this is a classic scam. (i.e., actually the meter was certainly not reset from a previous fare and I would have paid much more than I should have)
I have nothing to substantiate what I telling now, but this left me with the feeling that, in a way, the hotel clerk was an accomplice to that scam. He didn't seem to bother at all. He didn't try to protect or warn me even when it was obvious. He should have spontaneously asked me to get out of the taxi. He seems really detached by that and was ready to let me go with this taxi driver. So my feeling is that he got a cut in that.

I used several time this taxi solution (hail from the hotel) and never had an issue. It happens only on my way to the airport, because it is of course easier to foul a customer with THB 200 on a THB 300 fare than on a short fare within the city.

The apartment is 3 minutes walk from the main road, and I would advise you to walk until there and order the taxi by yourself.
